Question

I have written the following script below – I am not quite happy with the script as I think it could be written in a more elegant and dynamic way…

I am using ftp.exe to ftp files from my application to another server.

If the folder structure does not exists on the web site. I need to create the folder stucture…

and doing it this way

mkdir folder1
mkdir folder1/folder2
mkdir folder1/folder2/folder3

with the script below I cater for a few folder lengths but not unlimited… so the solution will only work up to a certain amount of sub folders.

ftpmkdirlength = ftpmkdir.split('/').length-1
var i=0;
for (i=0;i<=ftpmkdirlength;i++)
{
ftpmkdir0 = " mkdir " + ftpmkdir.match(/\/.*?\//) + "\n";
ftpmkdir1 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\//) + "\n";
ftpmkdir2 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir3 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir4 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir5 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir6 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir7 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir8 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir9 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir10 = " mkdir " + ftpmkdir.match(/\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\/.*?\//) + "\n";
ftpmkdir1 = " mkdir " + ftpmkdir + ftpmkdir0 + ftpmkdir1 + ftpmkdir2 + ftpmkdir3 + ftpmkdir4 + ftpmkdir5 + ftpmkdir6 + ftpmkdir7 + ftpmkdir8 + ftpmkdir9+ ftpmkdir10;
ftpmkdir1 = ftpmkdir1.replace(/mkdir null/ig, '');

How can I make it more dynamic? so that the script see how many folders the input contains…

I can see the folders full length and get the folder like this /folder1/folder2/folder3 but need to strip it to

folder1
folder1/folder2/
folder1/folder2/folder3/

and then create it…

You can use a loop, checking for indexes of '/' and using them to get parts of the full path.

var cmd = '';
var j, k;
var subpath;

if (ftpmkdir.length < 1 || ftpmkdir === '/') {
    throw 'no path';
}

j = ( ftpmkdir.indexOf('/', 0) === 0 ) ? 1 : 0; // provides non-slash starting point
k = ftpmkdir.indexOf('/', j);

while (k != -1) {
    subpath = ftpmkdir.substr(j, k - j); // get the path up to the current slash
    cmd += " mkdir " + subpath + "\n";
    k = ftpmkdir.indexOf('/', k + 1); ; // move the cursor
}

// check for additional path after last slash mark
if ((subpath + '/').length !== ftpmkdir.length - j) {
    cmd += " mkdir " + ftpmkdir.substr(j, ftpmkdir.length - j) + "\n";
}
